Disturbance and biotic resistance are important factors driving plant invasions but how these factors interact for plants with different modes of colonization (i.e., sexual and asexual) is unclear. We evaluated factors influencing the invasion of...

The rapid expansion of the non-native genotype of Phragmites australis in wetlands in North America has raised questions about what factors control its establishment and whether Phragmites response to these factors varies among populations. We...

Aims We use a regional comparison of Phragmites australis (common reed) subsp. americanus, P. australis subsp. berlandieri and introduced P. australis (possibly five sublineages) in the Chesapeake Bay, the St Lawrence River, Utah and the Gulf...

The aim of this research was to determine whether permanent and nonpermanent plots for describing riparian plant communities would yield the same results. This research was conducted at 4 streams in central eastern Idaho. Permanent and...

Beginning in 2003, a non-native subspecies of Phragmites australis, a wetland grass, invaded the Platte River in Nebraska, USA. The plants' dense root and rhizome structures caused channel narrowing and increased deposition of fine sediment. We...

Background/Question/Methods An exotic haplotype of Phragmites australis is rapidly invading wetlands across North America where it can form large monotypic stands and out-compete native vegetation. In the Chesapeake Bay, Phragmites is more...

Utah is experiencing a dramatic invasion of an aggressive European subspecies of the common reed (Phragmites australis subsp. australis). This invasion is threatening recreation resources, wildlife habitat, and native wetland ecosystems. In this...

Species distribution models rely on the assumption that species' distributions are at equilibrium with environmental conditions within a region – i.e. they occur in all suitable habitats. If this assumption holds, species occurrence should be...

Carex species, common dominants of wet meadows and widespread in ecosystems in the northern hemisphere, seldom naturally recolonize drained wetlands following hydrologic restoration. We conducted a seedling emergence experiment with five Carex...

During the Anthropocene, the rapid spread of invasive species into new habitats has repeatedly led to major ecosystem change. Invasive species succeed by outcompeting native species or significantly altering the physical or chemical properties of...

Successfully managing wetlands requires monitoring changes in plant community composition. We used remote sensing techniques to document the replacement of desirable native wetland vegetation with invasive species in response to catastrophic flood...

This study presents a systems modeling methodology to determine the quantity of water to supply among wetland units to increase ecological performance. Ecological performance is measured by a parameter defined as weighted usable area for wetlands...

Natural and anthropogenic site characteristics play a role in determining the current distribution of invasive plant species. An understanding of these characteristics can be used to prioritize areas for monitoring and control efforts and to...

In prairie wetland restorations, seeds may be limiting plant recolonization but this has never been quantified in the field. We evaluated the seed rain in restored and natural wetlands to determine if seed limitation constrains plant...

Background/Question/Methods Phragmites australis is invading wetland communities across the United States and has resulted in declines of native plant and animal diversity and alterations to nutrient cycling. Our objective was to understand how...

Background/Question/Methods
The introduced haplotype of Phragmites australis is an aggressive invader and has a negative effect on many aspects of wetland ecosystems in North America. In Chesapeake Bay subestuaries it was more abundant and had...
